Interaction between turkey monocytes and avian Chlamydia psittaci in the presence of Mycoplasma sp.: the importance of nitric oxide1192
in turkeys, this interaction, through the pivotal role of NO, might influence the outcome of respiratory diseases in turkeys Service: Quality of laboratories Kwaliteit van laboratoria Qualité des ...
Dietary L-carnitine supplementation increases antigen-specific immunoglobulin G production in broiler chickens.
immunization. No significant influence of the sex of the chicks or the imposed environmental temperature on Ig responses was found. Temperature treatment and sex, but not L-carnitine supplementation, did ...
Nested designs in ruggedness testing
expected mean squares. Very frequently, negative variance estimates were obtained. Their absolute values were found to be dependent on the influence of the factor examined below it in the design, on the ...
Neomycin: microbiological assay or liquid chromatography?36676
diffusion (RSD:41%) and 56% by turbidimetry (RSD: 50%). This confirmed that the presence of neomycin C in a neomycin sample influences the reproducibility of the microbiological assay. T estimate the ...
Oxygen radicals and nitric oxide production by turkey respiratory macrophages
Respiratory Burst response result results Salmonella Salmonella enteritidis specific treatment Turkeys Universities university veterinary Zymosan Abstract: The influence of different induction protocols on the ...
Induction of cytotoxic T-cell responses against culture filtrate antigens in Mycobacterium bovis bacillus Calmette-Guérin-infected mice.
phenyl-Sepharose CL-4B. Our results indicate that MHC-linked genes exert a profound influence on the generation of CD8 + CTL s following BCG vaccination. Service: Réponse immunitaire Immuunrespons Immune response ...
Ruggedness tests on the high performance liquid chromatography assay of the United States Pharmacopoeia 23 for tetracycline.HCl: comparison of different columns in an interlaboratory approach
procedure were examined on qualitative responses by performing half-fraction factorial designs at three different ages on each column. The influence of column ageing was separately evaluated by injections ...
Factors influencing between-laboratory variability of C-reactive protein results as evidenced by the Belgian External Quality Assessment(EQA) Scheme29
Participants using homogeneous systems with several calibration points generally achieved better performance. Working temperatures influenced the results to a lesser extent. The present study stresses the ...
Role of YadA in resistance of Yersinia enterocolitica to phagocytosis by human polymorphonuclear leukocytes55
chemiluminescence response to Y. enterocolitica mutants affected in the known pYV-encoded factors. We did not detect any influence of the Yops in this phenomenon. By contrast, the presence of YadA correlated with ...
Experimental design on liquid chromatographic parameters in the analysis of tetracycline on poly(styrene-divinylbenzene)
4-epianhydrotetracycline (EATC). By means of a half-fraction factorial design, the importance of the individual chromatographic parameters and parameter interactions of this LC method was examined. The influence on the ...
